Subject: Merge in two patches from Dave Cinege:     the first is a cleanup of
 tar --exclude     the second changes mount so mtab works more as it should,
 and     also allows mount to use the traditional short form (i.e.     'mount
 / -o remount,rw' now works.

While inside tar, I changed it to use getopt...

+ *		single mounts from fstab. Can override fstab options for single
+ *		mount. Common mount_one call for single mounts and 'all'. Fixed
+ *		mtab updating and stale entries. Removed 'remount' default.
